Abstract
An LSP synthesizer (Line Spectrum Pair) includes an LSP voice synthesizer digital filter arranged for parallel operation upon voice parameters and excitation information, to obtain an LSP synthesized sound. The LSP voice synthesizer digital filter includes at least a parallel multiplier and a parallel adder. The parallel multiplier divides data into a set of upper bits and a set of lower bits and multiplies the upper and lower bits separately at specified different timings. The multiplication results are supplied to a delay circuit which adjusts timings of the multiplication results. These multiplication results are synthesized by the parallel adder to obtain a single piece of data.
